Channeling welding roller
Channeling welding roller at the basis of adjustable roller frame will be made of the driven wheel frame lift, use photoelectric encoder detects workpiece runout, the system controller to control the movements of the driven wheel. Displacement detector placed at one end of the workpiece holder, detect wheel pressure on the end face of the workpiece (end must be processed), detection wheel can rotate with the workpiece when the axial movement of the workpiece, the workpiece detection wheel will vary along with the move, optical encoder detects the direction of the workpiece runout and ran, the signal input to the system controller for processing. The controller will be adjusted according to the size of the driven wheel runout travel lift, lifting speed and lifting interval control up or down according to traverse direction. Runout of the workpiece is always in -1.5mm and + 1.5mm between the fluctuations, so that runout of the workpiece is limited within a certain range, to meet the needs of the welding.
